Today most large passenger planes can cross the Atlantic Ocean in less than seven hours and the fastest airplane can ( fly) (26) at more than 3,000 kilometres per hour. This is three times faster than the speed of the sound. People once ( believed) (27) that planes couldn’t fly faster than sound. This (has become) (28) possible since 1947 when an American pilot (to broke) (29) the sound barrier. Aircraft are the fastest way to travel because they fly straight over mountains and oceans. They have lots of modern technology, such as computers, to help them be fast and safe and are made) (30) of special strong, lightweight metals and plastics. Space flight is now a reality and not just something we (read) (31) about in books. The first space flight (took) (32) place in 1957. Two inventions made space flight possible. The first was the rocket engine, which can work in space and now it (has reached) (33) speeds of over 28,000 kilometres per hour. The second was the computer, which is needed to guide the spaceship once it is away from Earth and up in space. People can make long space flights on space stations and may stay there for weeks or months. If you look at the sky through a telescope you will find a lot of satellites that (are orbiting) (34) our planet at the moment. And the future? Who knows? There is no end to inventions and progress. Maybe we (willbe able) (35) soon to buy a ticket for a Moon flight!
1. Tomorrow we are leaving for Scotland, then we are visiting my family in Ireland and we are leaving at the end of the week. 2. Are go you doing anything tonight? Nothing special, why? Will you to the cinema with me? 3. I've bought a lot of books. Now I'm sudying. 4.This is the last time I've disappointed you. I won't do it again. 5. In ten years everybody has their own computers and access to the Internet. 6. The Pope is visiting the countries of South America. 7. Where are you? We are all waiting for you! I'm leaving! 8. She's having a baby next week. 9. Hurry up! The lesson is starting in two minutes!
